The city is dismantling a series of recently-erected 10-metre-high wind turbines along the Lake Ontario shoreline amid fears they could fall on beachgoers.
A Huron Wind Vestas V80 1.8MW turbine was damaged by high winds off Lake Huron north of Tiverton on May 4, 2018. A worker at a neighbouring facility captured the image of the tip of the turbine blade broken and dangling from the structure.
A single faulty blade is being blamed for a wind turbine collapse that occurred in Raleigh Township earlier this year.
TerraForm Power said 22 of its 52 turbines are back online
Vern Martin, a mechanical engineer and vice-president of Flowcare Engineering consulting company in Cambridge, Ont., believes a blade may have malfunctioned and struck the column, causing it to buckle. "That ... has actually been recorded as occurring before in some of these other failures," explained Martin.
A company in Chatham-Kent, Ont. has shut down all 51 of its wind turbines as a precaution until an investigation reveals what caused one of the turbines to collapse last Friday. The turbine in Raleigh Township, near the corner of Drake Road and the 16th Line, collapsed on itself.
The toppled turbine was discovered by a hunter scouting for coyotes early this morning in Harwich Township, according to The Blenheim News Tribune. The huge turbine blades and motor assembly crashed to the ground and the support structure appear to be folded in half.
No injuries were reported after a wind turbine in South Kent collapsed early this morning, causing a huge outcry of concern from the public on social media.
WindShare's own blog about the Exhibition Place turbine shows it has been plagued with problems over the past five years. The issues began after the turbine's main bearing was replaced in 2011. ...A series of what the operators called "cascading faults" took the turbine off line from the summer of 2012 until March 2013.
One of the wind turbines at Ferndale has been tethered after it was found to be leaning
NextEra Energy acknowledged Wednesday that it shut down some of its Ontario turbines and warned landowners after it was discovered a part on spinning blades could fly off. NextEra said the potential problem was with "a small thin plastic attachment" on the turbine blades that could separate while in operation.
Jodie Bird, another NextEra spokesperson, recently spoke with the Sarnia Observer said one of the turbine's 50-meter-long blades "snapped" during a storm, and Bird initially suggested lightning might be to blame for the damage.
Lightning is the likely culprit after a wind turbine blade snapped amid a storm late Sunday into early Monday, near Grand Bend, a NextEra spokesperson says. One of the towering turbine's three 50-meter-long blades was dangling Tuesday.
An anti-wind turbine group was circulating a photo of a turbine in the Grand Bend area, possibly damaged by Sunday’s severe thunderstorms.
